Product Overview




Molecular sieve 4A introduction: 

Molecular Sieve type 4A (Angstrom) is an alkali alumino silicate, obtained through synthesis of type A zeolite in sodic form. it is the sodium form of the Type A crystal structure. 4A molecular sieve has an effective pore opening of about 4 angstroms (0.4nm). Galaxychem type 4A molecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger.



Deep drying of air, Natural gas, alkane and refrigerant. 
Generation and purification of argon. 
Static dehydration of electronic element, pharmaceutical and unstable materials. 
Desiccant for paint, dope and foul etc. 
Type 4A molecular sieve is typically used in regenerable drying systems to remove water vapor or contaminants which have a smaller critical diameter than four angstroms.



Molecular Sieve 4A can be revived for reuse and the required factors for revival are temperature and pressure. To remove the adsorbed moisture and other materials, the revival condition shall be set up considering the features of target material and processing environment. The general revival temperature of Molecular Sieve 4A is about 200-300°C.
